Steam enters the high-pressure turbine of a steam power plant that operates on the ideal reheat Ranking cycle at 6 MPa and 350C. Steam is then reheated to 350C at 4 MPa before it expands to a pressure of 10 kPa. Heat is transferred to the steam in the boiler at a rate of 6104 kW. Steam is cooled in the condenser by the cooling water from a nearby river, which enters the condenser at 7C. Determine the total rate of heat input in the boiler vf @10kPa = 0.001010 (m^3/kg) Tsat @10kPa = 45.81 (C) sf @10kPa = 0.6492 (kJ/Kg.k) sfg @10kPa = 7.4996 (kJ/Kg.k) hf @10kPa = 191.81 (kJ/Kg) hfg @10kPa = 2392.1 (kJ/Kg) a. 2993.451 kJ/kg b. 2948.223 kJ/kg OC. 2785.56 kJ/kg d. 2912.190 kJ/kg T /1 6 MPa 10 kPa 4 5 6 Steam enters the high-pressure turbine of a steam power plant that operates on the ideal reheat Ranking cycle at 6 MPa and 350C.
